[tex]\scriptsize\circ[/tex] Texture and composition are the two criteria are used to classify igneous rocks.
[tex]\scriptsize\circ[/tex] Igneous rocks are classified based on texture and composition.
[tex]\scriptsize\circ[/tex] Texture describes the physical characteristics of the minerals, such as grain size. This relates to the cooling history of the molten magma from which it came.
[tex]\scriptsize\circ[/tex] Composition refers to the rock’s specific mineralogy and chemical composition.
